(Florida State University) A Florida State University professor used an electron microscope to capture the first three-dimensional image of a tiny filament, or strand, of an essential muscle that the palm-sized water bug Lethocerus indicus uses to fly. This filament is made of chains of a protein called myosin, which produce the power needed to contract muscles. This image shows for the first time the individual molecules in the filament in a relaxed state, which is necessary to re-extend muscles.read more
